Jurassic Endemism of Saudi Arabian Foraminifera and their Migration Routes among Intra-shelf Basins

A. Al-Dhubaib¹

Abstract

The faunal differences, including foraminifera, from the Arabian Plate and other Tethyan regions in the Jurassic, allow the identification of this part of Tethys as an Arabian Province. These particular differences span the Bajocian (and maybe earlier) to Kimmeridgian (and maybe later) times, when several successive endemic taxa evolved.

Endemic species have very limited geographical distribution and, consequently, constrained biostratigraphy due to isolation by either a geographical or ecological barriers.
